Sir – The Blenheim Flower Show (June 20-22) was OK as shows go. Unfortunately, there was a minimum number of exhibitors who accepted credit cards. This also included the restaurant, where you could get a three-course meal, but only if you had advance tickets or wanted to pay cash.

There was the option to turn around and go into Woodstock to a cash point, but if I had done that, it was unlikely I would have returned.

If this is going to be the case at each event Blenheim holds, they need to put a huge sign outside, saying ‘CASH ONLY’ Best of luck for the CLA Game Fair.
